terial'saturatedwit-h some volatile ini-lam! mable liquid such as gasolene, so that if the spark-producing element be struck 'or rubbed by a suitable substance ai 'spark will be produced to light the vapor Afrom the gasolene.

The object of my present invention is to provide a. simple, convenient and' easily v operated-device ofthe class referred to having provision for adjusting a spark-producingelement as it wears away.

To this end, my invention consists in the novel features of construction and in the combination and arrangement of parts set forth in the following specification and particularly pointed out inthe claims.

Referring to the drawings: Figure 1 isa central sectional View of an igniting device embodying'my invention with the cap in the position which it occupies when the igniter is placed in the pocket and is not in use for lighting purposes. Fig. '2 is a sectional. view .taken on line 2-2 of Fig. 1.y

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring to the form of the invention which is illustrated in Figs. 1 to 4,inclusive, the numeral 10 designates generally a casing consisting of two parts 11 fand 1 2 coaxially arranged to rotateone upon the other, said ycasing having a closed end 13 and an open end 14. The two parts 11 and l2 are held against longitudinal displacement by any suitable means such, for example, by rolling the circumferential wall of both parts inwardly to form intererlgaging ,corrugations 15 and 16 on vthe parts 11 and 12, respectively. Located within the casing 10 is a spark-producing element 17 formed of well kno-wn alloyv for this pur'- pose and within the casing there is also pro'- vided a body of suitable absorbent material 18 as; for example, absorbent cotton, which may be saturated with gasolene or other inflammable liquid which will vvaporize readily. The igniting element 17 is providedy with suitable means of adjust-ment whereby the same may be' adjusted at will to vary its position withrespectA to the open end 14 of the casing 10 and preferably this adjustment is accomplished by relative rotation of the two parts 11 and 12-of the casing in the following manner. Located ywithin and secured to the part 11 is a nut 19 having screw-threaded engagementl with a screw 2O both co-axially arranged with respect to the'casing 1'0. The spark-producing element 17, it willbe observed, is lcated at one side of the axis of the casing 10 and of the screw and nut 19 and 2O and in addition, said element-is' disposed -atan angle to said axis. The upper end of the element 1-7 is guided by a guide 21 secured to the interior of the part 12 and said guide and said spark-producing element are polygonal or some other suitable cross sectional shape so as tov prevent the sparkproducing element from'rotating within the guide. ln the present instance, the-sparkproducing element is square in cross section and the guide 2] is 'suitably shaped, as shown in Fig. 3. The spark-producing element 17 is connected to the screw 20 by suitable means whereby when arelative rotative movement is imparted to the' parts 11 and 12 the spark producing element rotates the screw 20 in the nut 19 and consequently the spark-producing clement is moved longitudinally by the guide 21 and for this purpose the spark-producing element is connected to the screw by a flexible coupling consisting of a helical springv22 screw ed onto the screw 20 and interengaging with the threads thereof, as shown somewhat enlarged in Fig. 4, while the upper portion of the spring encircles a shaft 23 which may be provided with suitable corrugations or indentations 24 to receive the convolut-ions of the spring- 22, while, in turn, said shaft` is connected to the igniting element, by a similar flexible coupling attached to said shaft and to said spark-producing element in a similar manner. Thus it will be seen that while the spark-producing element 17 bears an angular relation to the screw20 and although the angle' increases as the screw is moved upwardly to feed the sparkproducing element upwardly, the flexible coupling 22 and the flexible coupling 25 will provide for the proper relative motions be.

` scratching element 28 upon the'igniting element 17, after which the scratching element is rubbed across the end of the igniting element toward the right, thus producing a spark which will ignite the'vapor from the open end of the casing 10.

Referring now to the formof my invention'which is illust-rated in Figs. 5 to 8, inclusive; the numeral 29 designates generally a casing consisting of two parts 30 and 3l coaxially arranged and mounted to rotate with respect to each other, said parts being held against 'relative longitudinal displacement by interengaging corrugations 32 and 33 similar to those hereinbefore described. Located within the casing 29 is an igniting element 34 consisting of a suitable alloy well known to those 4skilled in ythe art for this purpose,

said element being located at one side of the median axial line of the parts 30 and 3l and being guided by a suitable guide 35 which,

in the present instance, consists of a tube which is circular in its upper portion, as shown in Fig. 7, and is cut away therebelow so as to be semi-circular, as shown in Fig. 8, fora purpose which Will presently appear. Located within and secured to the part 30 is a nut 36 having screw-threaded engagement with a screw 37 coaxially arranged-with respect to the casing 29 and having formed thereon or secured thereto a. crank-arm 38 to which the ignit-ing element 34 is attached in any suitable manner, whereby when a relative rotation is imparted to the two-parts 30'a`nd 31 of the casing 29 the screw 37 is ro-v tated within the nut 36 andconsequently a longitudinal feeding movement is imparted to the igniting element 34. Thus it will be evident that by grasping the two parts of the casing and turning the same in opposite directions the spark-producing element 'may be fed out of the open end of the casing as said element wears away when in use, The

casing may be provided with a suitable cap 39 carrying a 'suitable scratching element 40 which will be utilized to strike a spark in thesame manner in which the spark is produced by theiirst form of my invention he'reinbefore described. y

Referring nowto Fig. 9, wherein I have shown a second modified form of my invention, the numeral 14 designates generally a casing tormed-inttwo p arts 42 and 43 coaxially arranged-to rot-ate one upon the other, said casing' having a closed end 44 and an open end 45.` The two parts 42 and 43 are held against longitudinal displacement by any suitable means such, for example, as by' means of interengaglng corrugations '45 and 4G. Preferably, the part 42 is extended laterally somewhat to form a flange 47 which may be round, as shown, so that it may readily be turned with the fingers.A Located within the casing 41 is a spark producing element 48 and within said casing there is also provided abody of suitable absorbentmaterial 49 which, of course, will be saturated with gasolene or other suitable li'quid.' the same as the forms hereinbefore described. The igniting element 48 is provided with ameans of adjustment consist-ing of a nut Qisecured to the part 42 and havlng screw-threaded engagement with a. rod

51 whosescrew-threaded port-ion is coaxiallyv arranged with thecasing 41, said rod being provided with an oifset portion 52 which is guided by a guide 53 secured-to the part 43 of the casing.. To the upper end of the ott'-v set portion 52 the igniting element 48 is'secured by any suitable means as, for example, a coupling 54 consisting-of a helical spring. ln this form of my invention also, the igniting element as it wears away is adjusted by rotating the two parts of the casing with respect to each other. As a means for preventing the offset portion 52 from turning in the guide 53 as the two parts of the casing are rotated with respect to each other, said offset portion is made square and the guide correspondingly square, the same as in the form shown in Figs. 1 and 3.

Having thus described my invention,what

.I claim and desire by Letters Patent to seducing element mounted in said casing adjacent to said oriee, a screw .and nut operated by the relative rotation of. said parts for adjusting said spark-producing element. with `respect to said orifice, and a mass of absorbent material in said'casing. l 3.
